llo tilt 'whom 'it 'may concern:

le it known that l, Jesse O. MGCREERY, a citizen of the United States, and a resident of Fort Morgan, in the county oi? Morgan and btate of Colorado, have invented an improved `Hay-letaining Device for Haybtaclcers, of which the following is a 'specilr cation.

ln a well known class of apparatus for use in stacking hay, al series of parallel teeth are pivoted to a head :forming part of the lrame o1' the stacker which rests on the ground. The hay is carried up to the stacker and deposited thereon by what is commonly termed a bull, or sweep, rake. The teeth of the stacking apparatus have been provided with pivoted ingers for retaining the hay thus deposited thereon, said devices being adapted to releasethe' hay when the teeth of the stacker are raised for throwing the hay backward.

My invention is an improvement in the construction and attachment of the hay-re 'taining ingers.

The details of Construction, arrangement, and combination of parts are as hereinafter described and illustrated in the accompanying drawing, in whiclr- Figure l is a side view ot' a stacker and a "bullf7 or sweep, rake such. as commonly used for depositing lia-y on the stacker. F ig. 2 a perspective view of one of the teeth'of the stacker provided with my improved attachment. Fig. 3 is a side view of the parts shown in Fiu. 2 save that a Jortion of the side guard is broken away. Fig. t is a plan view of the parts shownin Fig. 2. F ig. o is an enlarged cross section on the line 5 5 of F ig. et.

In Fig. l, A indicates the frame of the stacker, and B the teeth thereoie which are pivoted to the frame and adapted to be raised from a horizontal, to a vertical, position, this being commonly efected by a rope C passing over pulleys D, D. To each of the teeth B my improved attachment is applied in thefollowi'ng manner. E indicates what is commonly termed a finger, the same constituting the hay-retainingl device proper 'instead of being pivoted, as usual in this class of devices, ina slot formed in the tooth B, which obviously weakens the latter, it is pivoted on the side of the tooth, the

ypivot being a screw bolt F-which passes through a guard pla-te Gr, as shown best in Fig. This guard plate is constructed of stout strap iron and the body thereof is spaced from the tooth B, its ends'loeiligsecured by clevises g. A spiral spring H, see Fig.- 5, is applied -to th'l screw holt F anda nut I erves to compress the same. The linger E .isf'arraiiged between the spring and a mit J which spaces it fromA the side of the guard G, and also secures the mit in place. The finger E is provided with a slot, or ei'ilarged opening, to receive the bolt. The spiral spring K, see Figs. 2,3, d, is connected with the tinge'r E on one side and a corres ondinu' s )rin K on the otherv P s l B,

side. Each spring is further connected "with the guard by means or' a bar or narrow plate L, the same'being pivotedto the guard plate.

.Xt a` point above the guard plate the finger E is provided with a lateral bend @,fso that the upper portion thereofis carried inward Vand thereby brought nearer alinenient with the side of the tooth B. It is apparent that, by means of the springs H, K, K, the finger ll is held normally in upright position, but thatv when sulii'cient force is applied the springs yield so that the finger may be moved iii any direction, and may in fact describe a circle. Thus, `when the bull rake M is run up over the. stacker teeth B, for the pur.

pose of depositing hay thereon, the fingers E Iwill be pressed backward as shown by fullh lines Fig. 5, and when the rake is run back, leaving the hay on the teeth B, the fingers E swing over to the inclined position shown vby dotted lines Fig. 3; and then, by the action ot' the springs K', they resume their normal vertical position shown in Figs. l, Q, et. rlhis adaptation o i the fingers E to swing` in either direction, also facilitates the discharge of hay from the teeth when the stacker is swung` up for iinloadingthe hayon the stack. in brief, the lingers can he car-- ried to an extreme inclination, oir/nearly 90" forward or back; but owing'rto the tact that the spring K is connected with the lingers at a higher point than the spring- K, a

greater pressure would be required to torce the ingers over4 toward the lpoints of the teeth B, rlhe fingers are provided with a series of openings to allow the point of attachment of the springs Kl to-be shifted in',`

order to increase or lessen the resistance 'of the fingers to such movement, so that they hold the hay on the teeth more ettectively than would otherwise be the ease.

The adaptation of the fiiie'i's for latei'al movement relative to the teth i3, indiniier end of the cated .by dotted lines Fig. 5, .is important, since it prevents their being injured bythe teeth' m of the sweep or bull rake-coming in contact with them when the rake is run up over the stacker, "so that there is no danger of the Vng'ers bein broken or, injuredv as would otherwise be t e case. The guard platel Gr 'also serves as a means for braking,

or arresting, the rake M, since the front` wheels of the latter come in contact with the inclined front ends of the guard plate when the rake is run up over the stacker. Thus the guard plates act as buffers prei yenting linjury to the fingers and the attachments thereof. Further, the inclination of the front ends of the guard plates' G tends to push the wheels of the rake laterally so that there is less liability of' injury to the tooth, a bolt passing through the same upon which the finger is loosely mounted, a spring applied to said bolt and pressing the finger laterally, and other springs connected with the finger on-opposite sides and arranged parallel tothe tooth, and means for connecting them with the guard plate whereby the finger is adapted to yield in every direction,y substantially as described. i h a stacker tooth,

3.- The combination, with al stacker tooth, of ahay-retaining finger, .a pivotbolt upon Which said finger is loosely mounted 'so thatl it may oscillate laterally, land a springapplied to said bolt and pressing against the finger whereby it tends to hold said finger vin a normally upright position, substantially as described.

Vof the hay-retainin attachment comprising a guard plate attac ed to the side of a tooth and the body thereof spaced from the tooth, a bolt arranged .in the space between the 'plate and tooth, a hay-retaining finger piv- Aadapted to yield inboth directions, su stanoted on .the bolt, and yielding means connected with the finger ,for holding it normally in an upright position, substantially as described.

' 5. The combination, with a stacker tooth, of a hay-retaining attachment comprising a side guard plate, a pivot'bolt, a`finger mounted rotatably thereon, springs conn ected with the linger and extending in opposite directions, and pivoted bars connect.-

ing said springs with the end portions of the guard, substantially as described.

6. The combination with a holder adapted to be secured to a stacker tooth, of a hay retainer consisting of a finger and two spiral springs on said finger near its lower end and adapted to be secured by their opposite ends in said holder.
